Nitrogen dynamics as a function of pH in soil cultivated with brachiarias
Abstract Brachiaria production is an important segment in Brazil's agriculture, used as a forage or animal feed. Studying the influence of Brachiaria sp. on soil nitrogen (N) dynamics under different soil pH and amendment conditions is a critical research need.

Aspectos da Reprodução em Brachiaria brizantha cv. Marandu [PDF]
Two modes of reproduction are found in plants, sexual and asexual. Apomixis is an asexual reproduction mode through seeds. Apomictic plants give rise to embryos identical to the mother plant through parthenogenesis of a non-reduced egg cell. This feature is very important to agriculture, once incorporated in genotypes of agronomic importance, it allows

Mistura de sementes de Brachiaria brizantha com fertilizante NPK [PDF]
As informações são contraditórias quanto ao tempo em que as sementes de Brachiaria brizantha podem ficar misturadas ao fertilizante NPK sem diminuir o poder germinativo das sementes. Assim, objetivou-se estudar o efeito de tempos de contato do adubo granulado NPK 04-14-08, com sementes dessa forrageira, na qualidade fisiológica (germinação e vigor ...

Calibration and evaluation of a carbon net primary productivity module based on the SIMPLE model
Abstract This study presents the carbon net primary productivity (CNPP) module, an implementation of the simple generic crop model (SIMPLE model) that we have extended to predict aboveground and belowground biomass production and carbon assimilation. The goal for this module is to predict biomass inputs at and below the soil surface, during and at the ...

Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters

Molecular Identification and Diversity of Fusarium spp. Associated With Sugarcane in Brazil
Seven Fusarium species associated with sugarcane in Brazil with moderate diversity and prevalence of F. sacchari. High genetic differentiation and haplotypes identified across Brazil, China and India via TEF‐1α analysis. ABSTRACT The genus Fusarium causes several diseases in grasses such as sugarcane and is characterised by high genetic variability and

As características estruturais da Brachiaria brizantha e Brachiaria decumbens foram estudadas em função de diferentes adubações. O estudo foi conduzido em casa de vegetação sendo avaliados dois cultivares de braquiária (B. brizantha cv. Marandu e B. decumbens cv. Basilisk) e cinco diferentes adubações (sem adubo, P, N, NP e NK).
